Definition

A space X is almost imgtex.fcgi?%5bres=100%5d%7b$%5cmathbb%7bR%7d$%7d%25.png -paracompact iff every open covering of X of cardinality imgtex.fcgi?%5bres=100%5d%7b$%5cle%5cmathbb%7bR%7d$%7d%25.png has an open locally finite refinement whose union is dense in X. It is equivalent to almost $\Aleph$-paracompactness.
